Genera

The Grapsidae are a family of crabs known variously as marsh crabs, shore crabs, or talon crabs.^[1] The family has not been confirmed to form a monophyletic group and some taxa may belong in other families.^[2] They are found along the shore among rocks, in estuaries, marshes, and in some cases pelagic among drifting seaweeds and flotsam.

Genera

A number of taxa, formerly treated as subfamilies of the family Grapsidae are now considered families in their own right, including the Varunidae and Plagusiidae.^[3] Forty species and ten genera remain in the family, two of the genera known only from fossils:^[3]

Geograpsus Stimpson, 1858
Goniopsis De Haan, 1833
Grapsus Lamarck, 1801
Leptograpsodes Montgomery, 1931
Leptograpsus H. Milne Edwards, 1853
Litograpsus † Schweitzer & Karasawa, 2004
Metopograpsus H. Milne Edwards, 1853
Miograpsus † Fleming, 1981
Pachygrapsus Randall, 1840
